TPA3251 is a high performance class-D power amplifier that enables true premium sound
quality with class-D efficiency. It features an advanced integrated feedback design and proprietary
high-speed gate driver error correction (PurePath™ Ultra-HD). This technology allows ultra low
distortion across the audio band and superior audio quality. The device can drive up to 2 x 175 W
into 4-Ω load and 2 x 220 W into 3-Ω load and features a 2 VRMS analog input interface that works
seamlessly with high performance DACs such as TIs PCM5242. In addition to excellent audio
performance, TPA3251 achieves both high power efficiency and very low power stage idle losses below
1 W. This is achieved through the use of 60 mΩ MOSFETs and an optimized gate driver scheme that
achieves significantly lower idle losses than typical discrete implementations.
